5 Claims.

This invention relates to the treatment of oil and more particularly toan improved method and means whereby water and gas is removed from oil.

An object of this invention is to provide an 5 improved method ofseparating the oil from water which is contained in the oil and, at thesame time, separating the gas from the oil so that the gas will notaffect the treatment of the oil, the gas being later returned to the oilafter the oil has been treated.

Another object of this invention is to provide a treating means forseparating oil from water or other undesirable elements, such as sand orthe like, and at the same time heating the oil 15 so as to facilitatethe separation of the oil from 25 provide an exceedingly simple treatingmeans of this character which can be mounted in a tank of suitable sizeso that any desired quantity of oil may be treated and so that theseparated water may be drawn off during the treatment of the oil.

The above and various other objects and advantages of the invention willin part be described in, and in part be understood from the followingdetail description of the present preferred embodiment, the same beingillustrated in the ac- 35 companying drawing, wherein:-

Figure 1 is a vertical section partly in detail of an oil treating meansconstructed according to an embodiment of this invention.

Figure 2 is a fragmentary sectional view taken 40 on the line 2-2 ofFigure 1.

Figure 3 is an enlarged fragmentary sectional View of one of the oiltreating nozzles embodied in this invention.

Referring to the drawing wherein like symbols 45 designate correspondingparts throughout the several views, the numeral Ill designates generallya heating tank or member provided with a head II, and a boss 13 throughwhich an intake oil discharging pipe 12 extends. A cap or gland memberI4 engages the boss or nipple l3 so as to seal the pipe l2 in the headII. A T or pipe connection I5 is secured to the upper end of the intakepipe l2 and a laterally extending oil sup- J55 ply pipe 16 is connectedat one end to a source of oil supply and at the other end to one side ofthe T IS.

The pipe l2 extends substantially to the bottom ll of the tank l0 andthe lower end of the pipe i2 is perforated or cut out, as at I8, and aplate 19 is secured to the lower end of the pipe I2 and contacts withthe inner side of the bottom ll. Preferably, there are a plurality ofteeth 25 on the sides of the cut out portion [8 and the bottom plate 19also has a plurality of upstanding teeth 2l. Preferably, this plate I9is relatively larger in diameter or size than the diameter of the pipel2 at the lower end thereof.

The tank 10 is adapted to contain water to substantially the lineindicated by the numeral 22 and oil to substantially the level indicatedby the line 23 which is substantially in line with an outlet pipe 24connected to the side wall of the tank It and also connected to astorage reservoir or the like.

A sight glass 25 is secured to the tank It at a point substantially withthe center of the sight glass in line with the top of the waterindicated by the line 22 and this water level may be maintained by meansof a water outlet connection 26 at substantially the bottom of the tankID.

A reducing connection 2! is connected to the top of the T and a branch28 is connected to a T or suitable pipe connection 29 secured to the topof the reducing connection 21. This branch 28 extends horizontally andthen vertically and downwardly, as at 30, and terminates in the outletpipe 24 so that the gas in the oil entering the connection 15 will risein the connections 21 and 29 and then pass horizontally and downwardlyand enter the cleaned or treated oil as this oil passes out of the tankIll and into the storage reservoir. A valve 3| is in the pipe 28 and aby-pass 32 carrying a pressure regulator 33 bridges the valve 3|. 3t and35 on opposite sides of the regulator or vent 33. A pressure gauge 36 isin the pipe 28 between the by-pass connection 32 and the T- connection29.

A chemical container 31 is connected to the T 29 by means of a pipe 38and a valve 39 is This by-pass 32 has valves open and project slightlyabove the water line 22 so that the heavy oil above the water line 22will be drawn downwardly and discharged through the jet means comprisingthe V-shaped openings 43 at the lower ends of the pipes 40. A pluralityof confronting teeth t4 are carried by the pipes 40 in the V-shapedportions @3 and the bottom plates 4| are also provided with upwardlyextending teeth 45 which are similar to the upwardly extending teeth 2|carried by the bottom plates [9. The heavy oil above the water line 22is drawn downwardly through the pipes 4% by means of steam jet members46 which are disposed inside the pipes 40 below the open tops thereofand these jet members 46 are connected as by radial branches 4'! to asteam pipe 48 which extends downwardly through the pipe l2 andterminates at a point spaced upwardly from the bottom plate l9 thereof.The pipe 48 is connected by means of a pipe 49 to a source of steamsupply and this pipe 49 connects with the pipe 48 through the wall ofthe pipe 12 exteriorly of the tank It].

The oil which is known as cut oil is pumped through the pipe l6 and thendown through the pipe l2. The gas in the oil will rise in the domelikeconnection 27 and then pass through the pipe 28 and the pressureregulator 33, the valves 34 and 35 being open at this time and the valve3| being closed. Steam will be discharged downwardly through the pipe 48from the steam, supply pipe 49 and the lower end of the pipe 48 isformed as a nozzle so that this steam will commingle with the downwardlymoving oil and heat the oil as it moves downwardly. The oil will bedischarged through the openings l8 in the pipe 1 l2 and the teeth 20 inthe sides of the openings I8 will break up the globules or bubbles ofwater so that oil contained in these globules or bubbles will be freedand permitted to rise upwardly as tree oil through the water in thebottom of the tank l0. At the same time, that the oil enters the tank I0through the pipe l2, the oil above the water line 22 will be drawndownwardly through the circulating members 49 and then reheated by steamdischarged from the steam jets 46. The steam will not only reheat thisoil but will also serve as a suction means to draw the heavier oil lyingjust above the water line 22 50 downwardly through the circulatingmembers 4%) and then force this oil out through the openings 43. The oilpassing through the openings 33 will pass between the teeth 44 on thesides of the openings 43 and will also pass through the teeth 45 carriedby the bottom plates 45. The light and completely treated oil will risein the tank IE) to the line indicated at 23 and then flow out throughthe pipe 24 into a suitable storage tank or may be disposed of in anyother convenient manner.

The quantity of water indicated by the line 22 may be maintained in thetank lEl by means of the outlet connection 26 which may have a suitablevalve interposed therein so that as the water rises in the tank It] theoutlet 26 may be drained to the proper point indicated by the sightglass 25 in order that no water will be disposed above the tops of theoil circulating members 4?].
